The Alberta Serious Incident Response Team (ASIRT) is investigating. Medicine Hat police are also looking into the actions of the 33-year-old injured suspect.

Three police officers involved in the shooting have been put on administrative leave while the investigation is underway.

This is the first officer-involved shooting in the southern Alberta city since the early 1980s, and Medicine Hat Chief of Police Andy McGrogan said it has left the force shaken up and shocked.
